Title: Oligomerization catalysts
Inventor: HILL THOMAS
IPC: B01J23/70
Filed: 1964-04-23
Abstract: Olefins are oligomerized in the presence of a catalyst which is prepared by heating Co(NO3)2 deposited on activated carbon substantially free from water to initiate an exothermic reaction, and maintaining the carbon at a temperature below 500 DEG  C. until substantially complete reaction has taken place.  The olefin may be ethylene, propylene, a butene or a pentene.  If desired two or more olefins may be co-oligomerized. Typical conditions for oligomerization are Temp. 80 DEG  C., Pressure 800 p.s.i.g., L.H.S.V. 0.1 to 5 vol./vol./hour.  Examples describe the oligomerization of propylene to hexenes.ALSO:Oligomerisation catalysts are made by heating Co(NO3)2 deposited on activated carbon substantially free from water to initiate an exothermic reaction, and maintaining the carbon at a temperature below 500 DEG C until substantially complete reaction has taken place.  The carbon made be maintained in a fluidised state by an inert gas, e.g. nitrogen. Alternatively the catalyst may be made by feeding carbon into the top of a column of inert gas wherein impregnation with Co(NO3)2 takes place followed by decomposition thereof and catalyst is collected from the base of the column.

[Also in Groups XIX and XL(c)] Fig. 4 shows an electron beam deflector tube 401 used in a circuit for producing a predetermined number of output pulses by multiplication from an input pulse, (see Group XL(c)). The beam 408 is normally incident on rest anode 406 a saw tooth pulse Je sweeps the beam over anodes 411 . . . 420 to produce negative output pulses from them which are fed to output line 404. The number of pulses in the output series is controlled by a blocking pulse on control grid 407 of the tube the duration of which corresponds to the time required by the beam to sweep over a given number of anodes. In the modification shown in Fig. 5, the beam deflector tube 501 has a slotted grid 508 and a common anode 504. The beam is deflected by saw tooth pulse Je so that it touches in turn the slots and bridges of grid 508 and produces a pulse series on the common anode 504 the number of pulses in the series being determined by the duration of the control pulse applied to the control grid 507.

Abstract: 915,301. Snap-action switches; unlatching switches. DOWTY ELECTRICS Ltd. June 1, 1959 [June 5, 1958], No. 17960/58. Class 38 (5). A lever-operated switch has an electromagnetically-releasable latch for locking it in one position but may be released in emergency by twisting the lever about its longitudinal axis. An insulating base 2 carrying four sets of three acts 45, 46, 47, located in four grooves 48, is attached to a cover member 12 by four metal bars 4 having a pair of upper cross-bars 5 and a pair of intermediate cross-bars 6. A metallic bush 7 pivoted on trunnions 11 in bars 5 is operable by a rod 8 extending therethrough and having a flattened knob 17 at its upper end. Spring-loaded balls 15 at the sides of slot 14 in cover 12 give the bush 7 a snap-action. Pins 66 extending from bush 7 engage slots in two levers 63 pivoted at 64 in cross-bars 6 to move a transverse pin 62 coupling the four insulating carriers 51 so that metal contact-strips 49 thereon bridge contacts 45, 47 or 46, 47. The carriers 51 are pressed downwards by spring steel wires 53 engaging small projections 54. A platform 32 is supported from two bars 4 by members 33 and carries an electromagnet 35 having an armature 38 pivoted in platform 32, counterbalanced by weight 41 and urged by spring 42 to the position shown in Fig. 1 wherein it engages a groove 44 around the lower end of rod 8 to lock the lever against pivotal movement until electromagnet 35 is energized. In an emergency, however, the knob 17 may be rotated to turn rod 8 and cause a pin 27 to depress the armature 38 clear of groove 44 and allow the switch to be operated. Spring-loaded balls 29 urge the pin 27 to the desired one of its extreme positions. A spring- loaded plunger inside the part 25 of rod 8 enters a hole in bush 7 (Fig. 4, not shown) when the knob 17 is turned to the emergency position and prevents it being restored. A cylindrical member 19 sliding on rod 8 is spring-loaded to engage in a double-ended keyhole slot 22 in an upper cover 13 and prevent accidental operation of the switch. An interior rubber cover 74 fits around bush 7 to prevent dust and the like entering the switch which is enclosed by a metallic shell 3, and has a lower rubber cover 68 enclosing the connections to the switch contacts.

Abstract: 1425283 Integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 24 April 1974 [4 June 1973] 17961/74 Heading H1K Replacement subcircuits, the external connection pads of which are in mirror-image relationship to those of corresponding subcircuits in an IC wafer comprising a large number of subcircuits, are face-bonded to the wafer with their pads in register with corresponding pads of subcircuits to be replaced and the replaced sub-circuits inhibited. A subcircuit may be replaced because it is defective or when a subcircuit of improved design or performing a different function is to be substituted for it. In general two sets of wafers are produced comprising subcircuits having input, output and power supply pads in mirror-image relationship. Each wafer is tested and those of each set having a high incidence of defective sub-circuits are used as sources of replacement elements for more perfect wafers of the other set. If a particular sub-circuit tends to be defective in a high proportion of wafers or is to be replaced by a different design in all wafers two sets of wafers respectively containing mirror-image sets of this sub-circuit or its replacement in multiple, or wafers containing single such sub-circuits are provided. As described each sub-circuit has interconnected inner and outer sets of pads and replacement is effected by bonding the outer pads of the replacement and replaced subcircuits after either severing the inner-outer pad interconnections of the replaced one and covering it with insulation or removing it by a laser cut inboard of its outer pads, the inner pads then enabling the removed sub-circuit to be further tested. Where adjacent sub-circuits are to be replaced they may be removed and replaced as a single unit.
